WHAT IS A SEMI-MOUNT?
“Semi-mounts” are a name given towards a mounting that’s only semi-completed. It’s not fully finished. It’s missing the center stone.
So whether you already have a diamond you want to set, want to buy a new diamond (or a bigger one), or even a gemstone like sapphire, ruby, emerald, morganite… these types of mountings are made for customization.
